AIR REGISTER.

Application filled September 6, 1923. Serial No. 661,246.

T 0 all whom it may concern.-

Be it known that I, EDWIN BEALE SADTLER, a citizen of the United States, and resident of Manhattan, city, county, and State of New York, have invented certain new and useful Improvements in Air Registers, of whichthe following is a specification.

This invention relates principally to an air register for use with liquid fuel burners, preferably of the atomizing type in which the fuel is finely atomized by mechanical means producing a hollow conical spray.

An object of the invention is to provide a register which may be fitted to any type of furnace and may replace the present type of standard Howden fronts, thus enabling a more rapid and cheaper conversion from coal burning to oil burning with consequent ready replacement of the Howden fronts if it is ever desired to return to coal burnanother object is to provide a device which will be held together and in position by a minimum number of bolts, so that it can be readily knocked down and shipped and again assembled by men not skilled inv machine work.

Another object is the provision of a register that may be readily used for either natural or forced draft and will provide a much greater amount of air than the previous standard types of register with con sequent ability to handle a larger amount of oil per burner.

' Other objects will be apparent from the following detailed description and the appended claims.

In the drawings:

Figure 1 is a front view of the register in position with a portion of the outer plate broken away.

Figure 2 is a section on the line 2-2 of Figure 1.

The furnace 1 may be of any usual or desired type and is provided with an opening 2 in its front. A furnace front plate 3 made to suit the diameter of the furnace-is cast with centering lugs t at various points about its periphery by which it may easily be placed in correct position in the furnace opening and which will also sustain a large part of the weight of the front plate and the parts attached thereto, thus relieving the holding bolts fro-m too great strain. Angle plates 5 are attached to the furnace and the front plate is fastened thereto by bolts 6. The front plate is also cast with a ring 7 on its outer face. for purposes hereinafter set forth.

Carried by the front plate and opening into the furnace is the mixing chamber 8 of generally tapering form as shown in Figure 2 and having a flange 9 by, which it is attached to the front plate.

An outer plate 10 is cast with a ring 11 on its inner side. A register front plate 12 is cast with a boss at the center for carrying the burner and is provided with the usual peephole 13. Bolts 141- pass through the flange 9 of the mixing chamber, the furnace front plate 3, the outer plate 10 and the register front plate 12 and are provided with nuts 15 by which all of these parts are held together. Pipe spacers 16 around these bolts 14: accurately position thefront plate '3 and. the outer plate 10 in proper relation to each other.

Bolts 17 pass through the outer plate 10, the ring 11, and are threaded at their inner ends into the ring 7 .on thefurnace front plate. 18 on doors 19 each of which doors is cast in one piece with the hinge lugs 18 and an operating lug 20 which has a slot 21 in its outer end.

There are preferably six of these doors and they close against the spacers 16 on the bolts 14. By adjustment of these doors the airsup'ply may be entirely out off, or a 7 These bolts also pass through lugs large amount may beadmitted. When the outer plate 10 and rides thereon. It is held in place between the outer plate and the lugs 18 of the doors. Six pins 23 are tapped into the same and one of these pins engages in each of the slots 21 of the operating lugs 20 of the doors. Obviously rotation of the ring will thereby adjust .the doors. To obtain this result, the ring 22 has rack teeth 24 on its outer edge for a short distance, and these mesh with apinion 25 which is operated by a hand wheel 26 and is locked in any desired position by a jam nut 27. An inclosing wall 28 may be connected to the furnace front plate 3 and the outer plate 10 to thereby inclose the air register doors and adapt the device for forced pressure.

The doors can be removed by taking out the bolts 17, while the register front plate 12 can be removed by taking off the nuts 1.5 and removing the plate 12 together with the burner carried thereby. If desired to further disassemble the parts, the bolts 14; will be removed. It is evident that the as.- sembly or disassembly is very simple and can be carried out without the aid of skilled mechanics. The parts cannot be assembled in wrong position.

It is obvious that various changes in the form and exact proportions of the parts may be made without departing from. the invention, and it is to be understood that the invention is limited only by the scope of the appended claims.

I claim as my invention 1. An air register which comprises a mixing chamber, a furnace front plate, an outer plate, and a front register plate, and securing means each member of which passes through all of these elements and hold them in assembled relation.

2. An air register which comprises a mixing chamber, a furnace front plate, an outer plate, and a front register plate, bolts which pass through all of these elements, and spacing devices on said bolts which hold the furnace front plate and the outer plate in proper relation when in assembled position.

8. An air register which comprises a mixing chamber, a furnace front plate provided with lugs which fit within the furnace opening and support a large part ofthe weight of the front plate and parts carried thereby, an outer plate, and bolts passing through the outer plate, front plate and mixing chamber and holding them in proper relation when assembled.

t. An air register which comprises a mixing chamber, a furnace front plate provided with lugs which fit within the furnace opening and support a large part of the weight of the front plate and parts carried thereby, an outer plate, bolts passing through the outer plate, front plate and mixing chamber, and spacing devices on said bolts to hold the furnace front plate and outer plate in proper relation when assembled.

5. An air register comprising a mixing chamber, a furnace front plate, a ring thereon, an outer plate, bolts passing through the front plate, mixing chamber and outer plate to hold said parts assembled, bolts passing through the outer plate and threaded into said ring, and doors mounted to swing on the latter bolts.

6. An air register comprising a furnace front plate, a ring thereon, an outer plate, bolts passing through both said plates, spacing devices on said bolts for holding them in proper relation, other bolts passing through said outer plate and threaded into said ring, and doors mounted to swing on the latter bolts.

7. An air register comprising av furnace front plate, a ring thereon, an outer plate, a register front plate, bolts passing through all three plates to hold them assembled, spacing devices on said bolts to hold the furnace front plate and outer plate in proper relation, other bolts passing through the front register plate, the outer plate, and threaded into said ring, and doors mounted to swing on the latter bolts.

8. An air register comprising a furnace front plate, a ring thereon, an outer plate, a ring thereon, bolts passing through said plates to hold them assembled, spacing devices on said bolts to hold the furnace front plate and outer plate in spaced relation, other bolts passing through the outer plate and threaded into the ring, doors swinging on said latter bolts and closing against said spacing devices, and means for adjusting the position of said doors.

9. An air register comprising a furnace front plate, a ring thereon, an outer plate, a ring thereon, means for holding the two plates assembled in spaced relation, bolts passing through the outer plate and threaded into the ring on the front plate, doors on said bolts, and adjusting means supported by the ring on the outer plate for varying the position of said doors.

10. An air register comprising afurnace front plate, a mixing chamber, an outer plate, a. register front plate, securing devices engaging all of said elements, doors mounted between the outer plate and the furnace front plate and adjustable to different positions, and means for inclosing the space between. the outer plate and the fur nace front plate to adapt the device for forced draft.

In testimony whereof I affix my signature in the presence of two witnesses.
